Hi Cheng

Still no success. I've got two nodes 192.168.0.2(client) and 192.168.0.4(server)
I bound orb-listener-1 on both machines to their network address:
<iiop-listener port="3700" id="orb-listener-1" address="192.168.0.2" lazy-init="true"></iiop-listener>
I can reach the server with the url http://192.168.0.4:8080/. The OS on both machines is fedora 14 64 bit with Glassfish 3.1.2.
The code in the client ejb is:

@Stateless
@LocalBean
public class CallEjbBean {
	
	@EJB (beanName="BankServiceBean")
	BankService bankservice;
---------------------------------------------
ejb-jar.xml:

<enterprise-beans>
    <session>
      <ejb-name>CallEjbBean</ejb-name>
    </session>
  </enterprise-beans>
---------------------------------------------
glassfish-ejb-jar.xml:

 <enterprise-beans>
   <ejb>
     <ejb-name>CallEjbBean</ejb-name>
     <jndi-name>CallEjbBean</jndi-name>
      <ejb-ref>
       <ejb-ref-name>BankServiceBean</ejb-ref-name>
        <jndi-name>corbaname:iiop@192.168.0.4:3700#ServerEAR/ServerEjb/BankServiceBean</jndi-name>
       </ejb-ref>
    </ejb>
   </enterprise-beans>
--------------------------------------------------------

I cannot deploy the application. The error I get is:
SEVERE: Class [ Lsession/BankService; ] not found. Error while loading [ class ee.example.ejb.CallEjbBean ]
